# Models

## How to connect

Both methods work, and you can enable them together:

-   **Subscription login**: sign in with an account you already pay for (Claude, ChatGPT, etc.) — no separate key needed.
-   **API key**: get a key from the provider's platform and pay by usage.

## Built-in providers

| Provider | Access | Built-in models |
| --- | --- | --- |
| Claude | Subscription login | Opus 5, Opus 4.8, Opus 4.7, Sonnet 5, Sonnet 4.6, Haiku 4.5, Fable 5 |
| Anthropic API | API key | Same as above (Opus / Sonnet / Haiku / Fable) |
| Codex | ChatGPT subscription login | GPT-5.6 (Sol / Terra / Luna), GPT-5.5, GPT-5.4, GPT-5.4 mini |
| OpenAI API | API key | GPT-5.6 (Sol / Terra / Luna), GPT-5.5, GPT-5.4, GPT-5.4 mini |
| DeepSeek | API key | DeepSeek V4 Pro, DeepSeek V4 Flash |
| Kimi (Moonshot) | API key | Kimi K3, Kimi K2.7 Code |
| Kimi Code (Coding Plan) | API key | Kimi K2.7, Kimi For Coding |
| Zhipu BigModel (GLM) | API key | GLM 5.2, GLM 5.1, GLM 5 Turbo, GLM 4.7 FlashX |
| Zhipu Code (Coding Plan) | API key | GLM 5.2, GLM 5.1, GLM 5 Turbo, GLM 4.7, GLM 4.5-Air |
| MiniMax (mainland China) | API key | MiniMax M3, M2.7 (incl. Highspeed), M2.5 (incl. Highspeed) |
| Xiaomi MiMo | API key | MiMo V2.5 Pro, MiMo V2.5 |

You can also add a custom provider by hand — just fill in a base URL and key, and Finch will detect the API type and fetch the model list automatically.

## Quick vs. Think

Every conversation can run in **Quick** or **Think** mode: Quick answers right away without much deliberation, for the fastest response; Think reasons before answering, is more careful, and lets you tune how deep it thinks (light / moderate / careful / deep). Not every model supports thinking — it depends on whether the underlying model has that capability.

## Different models for different tasks

Everyday chats and automation tasks can each use their own model and thinking level — for example, your best flagship model for daily use, and a fast, lightweight model for scheduled automation.
